Mirror from all ports to one

[emendezg92]

Hello, I have a switch catalyst 4500 with two boards of 48 ports each one, I need that all traffic of these ports can be reflected in a mirror port. Some of these ports are in different vlans, do you know if it's possible to do this? Also, this could affect processing?

Hi

Are you referring to create a SPAN?

You could configure, example:

monitor session 1 source interface FastEthernet 1/0/1 - 48 ,  FastEthernet 2/0/1 - 48  both
monitor session 1 destination interface GigaEthernet 1/0/1 

Always monitor the CPU utilization to avoid any impact,  Show process cpu history

Hope it is useful
